In the Blue Bloods episode “Erasing History,” while Nicky (Sami Gayle) surprises everyone by defending her activist friend Chrissie (guest star Naian González Norvind) who defaced a NYPD flag, grandpa Henry (Len Cariou) is a witness in a hit-and-run. Henry can’t help but to poke his nose into the case when his grandson Det. Danny Reagan (Donnie Wahlberg) is following leads. As usual, Danny promises the victim, Whitney, that he’ll find the person behind the crime.
Whitney is portrayed by Genevieve Angelson. She’s known for her roles on Good Girls Revolt (Patti Robinson, see link above), Backstrom (Nicole Gravely), and House of Lies (Caitlin Hobart), among others. Angelson was also in the 2015 crime drama True Story with James Franco and Jonah Hill. Blue Bloods airs Fridays at 10pm on CBS, right after Hawaii Five-0.
